[dccp] DCCP work ideas

2009-07-29 Thread Bryan Ford
In response to Pasi's tsvarea talk on where to go next with DCCP, I would like to offer two ideas for future DCCP work that could increase the its likelihood becoming widely used for something. 1. Get involved in the nascent multipath TCP work and develop a way to use DCCP as a better

Dear Bryan, DCCP's CCID's do probe for capacity for e.g. CCID 3 (which follows TFRC) would allow the sender to send upto twice the receiver rate or that allowed by the throughput equation (which ever is small) and hence its upto the application to decide whether to retract back to its

Hi Bryan, Thanks for the great suggestions for DCCP work :-). I'm quite interested personally in the multipath possibilities. I'd like to hear you expand a bit on how DCCP could be a control layer for multipath TCP. Flow control for apps with sending rates that are step functions is an

Hi Tom, Arjuna, On the step-function rate adjustment problem... Flow control for apps with sending rates that are step functions is an interesting nut. As Arjuna says, TFRC (CCID3) does allow the sending rate cap to grow to twice the current sending rate without demand from the app. And
